Re: [Xen-users] Bringing up xen on omap5432

Hi Chen,

ÂThanks for getting back. I actually used the TI's custom ROM code API (by passing 0x102 in ip and calling smc #0) to switch to hyp mode. Apparently this is TI OMAP5432 specific ROM CODE API call to make to switch into hyp mode. That worked for me and I am booting up linux DOM0. Now I am still trying to boot DOMU.

Thanks a lot for help.

Regards,

Surya

Sorry for the late reply, I am still on the vacation of Chinese New Year.

IIRC, the default u-boot shipped with the board doesn't work with Xen. And
you should be able to use the latest u-boot which contains the patch that
would let the processor switch to EL2 before booting the kernel/hypervisor.
(I suggest you double-check whether the "EL2 enablement' config is selected
of your u-boot. It might not be selected by default in the config of omap5.)

Cheer,

Chen Baozi
